Canadian Red Cross Standard First Aid Practice Test

When someone shows signs of opioid poisoning, the most critical action is to call emergency medical services (EMS) immediately. This is because opioid poisoning can lead to life-threatening respiratory depression and potentially fatal outcomes. Timely professional help is essential for providing the appropriate medical intervention, which may include the administration of naloxone (Narcan) to reverse the effects of the opioid.

This option prioritizes the health and safety of the individual by ensuring that trained medical personnel can assess and provide the necessary treatment. While other actions, like trying to wake the person or leaving them alone, may seem appropriate, they do not address the underlying medical emergency effectively. Additionally, giving someone water could pose a risk of choking if they are unconscious or semi-conscious. Overall, contacting EMS is the fundamental and life-saving response needed in such a situation.
